The term “double oak” is showing up on more and more bourbon labels, but not all of these bottles are created equal. While the basic concept is the same—aging the spirit in a second new barrel—the results can be dramatically different. The type of barrel, the length of the finishing period, and the character of the initial bourbon all play a huge role in the final taste. To help you find your perfect bottle, we’re doing a deep-dive double oak bourbon review, comparing popular mainstays with innovative craft spirits that are changing the game. We’ll break down the key differences in their profiles, where they stand in the market, and which one truly deserves a spot on your shelf.

What is Double Oak Bourbon?
If you’ve ever wondered what makes a bourbon exceptionally rich and complex, the answer might be a second barrel. Double Oak Bourbon is a style of whiskey that goes through a unique, two-step aging process. It starts its life like any other bourbon, aging in a new charred oak barrel. But instead of being bottled after that first maturation, it’s moved into a second, brand-new charred oak barrel for a final finishing period.
This second round of aging is where the magic happens. It allows the spirit to interact with fresh wood, pulling out deeper, sweeter, and more intense flavors that you wouldn’t get from a single barrel. Think of it as adding a second coat of paint—it deepens the color and adds a whole new layer of dimension. This meticulous process is what gives a Double Oaked bourbon its signature character, transforming a great bourbon into something truly unforgettable. It’s a testament to the craft, showing how patience and a little extra effort can create an incredible result. For whiskey lovers who appreciate a strong oak presence and a symphony of layered flavors, this style is a must-try, offering a sipping experience that is both robust and remarkably smooth.
The Art of Double Barrel Aging
The process of double barrel aging is a deliberate art form designed to build layers of flavor. After the bourbon completes its initial aging, it’s carefully transferred to a second barrel. This isn’t just any barrel; it’s specifically prepared to impart a different set of characteristics. This second aging period, which can last for around a year, allows the whiskey to soak up even more of the wood’s rich compounds. It’s an intimate dance between the spirit and the oak, where the extra time coaxes out notes of vanilla, caramel, and spice, creating a profile that is both powerful and beautifully balanced.
Toasted vs. Charred: What’s the Difference?
When we talk about the second barrel, it’s important to understand that it’s not just a repeat of the first. The key difference often lies in the treatment of the wood. While the first barrel is heavily charred, the second barrel is typically deeply toasted before receiving a light char. Toasting is a slower, lower-heat process that caramelizes the sugars in the wood, bringing out sweet, delicate notes of vanilla and baking spice. The charring that follows creates a layer that filters the spirit while adding classic smoky notes. This specific combination of toasting and charring is what creates such a unique and complex flavor profile in the final product.
How Double Oaking Builds Complex Flavor
So, what’s the payoff for all this extra work? An incredibly deep and complex flavor. The first barrel gives the bourbon its foundational notes of caramel and spice. The second, toasted-and-charred barrel builds on that foundation, adding layers of dark chocolate, toasted marshmallow, dried fruit, and rich oak. This process results in a bourbon with a velvety texture and a long, warm finish. The dual-barrel process creates a harmony of flavors that you just can’t achieve with a single barrel, offering a sipping experience that is both familiar and excitingly different. It’s a perfect example of how craftsmanship can shape the very soul of a spirit.
What Does Double Oak Bourbon Taste Like?
So, what exactly happens in that second barrel to create such a sought-after flavor? Double oaking isn’t just about adding more oakiness; it’s a process of transformation. It takes the foundational notes of a great bourbon and deepens them, adding layers of complexity, sweetness, and spice that you won’t find in a standard single-barrel spirit. The result is a bourbon that feels both familiar and entirely new—a richer, more decadent version of a classic.
Tasting a double oak bourbon is a full sensory experience. It starts with the aroma, moves to the complex flavors on your palate, and ends with a long, satisfying finish. Each step reveals a different facet of the spirit’s character, a direct result of its extended time interacting with charred oak. To truly appreciate it, you have to pay attention to how the notes evolve from start to finish. Let’s walk through the typical tasting profile of a quality double oak bourbon.
The Nose: Toasted Marshmallow and Rich Oak
Before you even take a sip, the aroma of a double oak bourbon tells a story. The first thing you’ll likely notice is a sophisticated blend of aged, charred oak and a hint of rich leather. But give it a moment, and sweeter, more delicate scents begin to emerge. Think of warm cinnamon syrup, vanilla bean, and juicy raisins. The most distinct note for many is a comforting, nostalgic smell of toasted marshmallow, the kind you’d get from a campfire. This beautiful balance of robust oak and dessert-like sweetness is the first sign that you’re about to taste something special.
The Palate: Vanilla, Caramel, and Dark Fruits
When you take your first sip, the flavors deliver on the promise of the aroma. The taste often starts with that familiar aged oak and leather, but it’s quickly joined by a wave of rich, sweet notes. Many people find the experience reminiscent of a s’more, with layers of chocolate, vanilla, and graham cracker mingling with a touch of smoke and cinnamon. You’ll also find deep caramel and hints of dark fruits like dried raisins or plums, all balanced by a gentle rye spice that keeps the sweetness from becoming overwhelming. It’s this intricate dance of flavors that makes each sip a new discovery.
The Finish: A Lasting, Spicy Warmth
The final act of a great double oak bourbon is its finish. This isn’t a spirit that disappears the moment you swallow. Instead, it leaves a medium-to-long, warming presence. The finish is where the oak and barrel char really shine, accompanied by notes of burnt caramel and spiced raisin. You might also detect a hint of tobacco or the lingering sweetness of a freshly baked cinnamon roll. It’s a dry, spicy, and incredibly satisfying conclusion that invites you back for another sip, letting you appreciate the full depth of its character.
From Standard to Standout: The Double Oak Transformation
What makes this complex flavor profile possible? It all comes down to that second barrel. By moving a fully matured straight bourbon into a second, newly charred oak barrel for additional aging, distillers create a much richer spirit. This finishing process amplifies the vanilla, caramel, and spice notes while smoothing out any harsh edges. This technique, once a novel experiment, has proven so successful that it has inspired many distilleries to create their own double-barreled products. It’s a testament to how thoughtful craftsmanship can transform a standard bourbon into a standout, luxurious experience, much like the innovative spirits found in the Mary Dowling whiskey collection.
Double Oak Showdown: How Do They Compare?
When you’re exploring the world of double oaked bourbons, two names often come up: Mary Dowling and Woodford Reserve. Both offer a richer, more complex experience than their single-barrel counterparts, but they get there in different ways. Understanding these differences is key to finding the one that best suits your palate. Let’s break down how these two premium bourbons stack up in a head-to-head comparison, where they fit in the market, and whether they justify their price.
Mary Dowling vs. Woodford Reserve: A Head-to-Head Comparison
The core difference between these two bourbons is the finishing process. Woodford Reserve Double Oaked moves from a standard charred oak barrel to a second, deeply toasted and lightly charred barrel for nearly a year, which imparts rich, sweet oak notes. Mary Dowling’s Double Oak Barrel also uses a two-barrel process, but it’s engineered to create a uniquely smooth and layered profile. Our award-winning whiskeys honor a legacy of innovation, and this method is key. While both are complex, a review of Mary Dowling often points to its exceptional smoothness and inviting character.
Where They Stand in the Premium Market
Both bourbons sit comfortably in the premium market. Woodford’s Double Oaked is a popular step up from its standard bottle, though some critics at Breaking Bourbon note it’s an “average value” for the price. It’s a reliable, accessible choice for a double oaked experience. Mary Dowling is positioned for the drinker seeking a unique flavor backed by a powerful story. It appeals to those who value meticulous craftsmanship and a spirit that defies convention. It’s not just about a second barrel; it’s about a legacy that makes each bottle a conversation piece.
Is It Worth the Price Tag?
Price is always part of the conversation. Woodford Reserve Double Oaked retails around $60, a premium for its extra aging step, making it a solid choice for a special occasion. With Mary Dowling, the price reflects the double barrel process, the heritage, and the meticulous care in every batch. It’s an investment in a distinct tasting experience. When you buy a bottle, you’re connecting with the story of the Mother of Bourbon. For those who value both exceptional taste and a rich narrative, the value is clear.
How to Best Enjoy Double Oak Bourbon
One of the best things about a truly great bourbon is its versatility. A complex, double-oaked spirit has so much to offer, whether you’re a purist who sips it neat or a creative mixologist. The rich, layered flavors developed through its unique aging process make it a fantastic foundation for all kinds of drinks. The key is to find the preparation that you enjoy most. Here are a few of my favorite ways to savor every drop.
Sipping Neat or On the Rocks
To fully appreciate the craftsmanship behind a double oak bourbon, your first taste should be simple. Pouring it neat—with no ice or mixers—allows you to experience the full spectrum of aromas and flavors, from toasted marshmallow on the nose to that long, spicy finish. If you want to soften it just a bit, add a single, large ice cube. This will chill the spirit and slowly release water, which can open up new layers of flavor without over-diluting it. As many bourbon lovers will tell you, it’s a versatile spirit that shines on its own. When you explore our whiskeys, this is the perfect way to get acquainted with their unique character.
Classic Cocktails Made for Double Oak
While delicious on its own, the robust character of double oak bourbon makes it a standout in classic cocktails. Its deep notes of caramel, vanilla, and spice can hold their own against other ingredients, adding incredible depth. The Old Fashioned is a perfect example. The bourbon’s inherent sweetness from the corn mash and extra time in the barrel means it pairs beautifully with a sugar cube and a few dashes of bitters. A recipe like the Double Oak Old Fashioned shows how the spirit’s complexity elevates a simple, timeless drink. The result is a cocktail that’s both familiar and remarkably rich.
Creative Cocktail Recipes to Try
Ready to experiment? Double oak’s bold profile is a fantastic playground for more creative cocktails. For something bright and refreshing, try a Double Oak Whiskey Smash. This drink balances the bourbon’s “toffee-caramel flavor and oaky vanilla notes” with the acidity of fresh citrus and mint, making it an ideal choice for a warm afternoon. If you’re hosting a gathering, a large-batch punch is always a crowd-pleaser. A recipe like Malcom Reed’s Royal Oak Punch, which combines double-oaked bourbon with apple cider and lemon juice, creates a festive and flavorful drink that lets the spirit’s character shine through.
Simple Mixers That Let the Bourbon Shine
You don’t need a fully stocked bar to make a great drink. Sometimes, a simple highball is all you need. The key is to choose a mixer that complements the bourbon rather than masking it. A high-quality ginger ale or spicy ginger beer can highlight the warm, spicy notes in the whiskey, creating a perfectly balanced drink. Club soda with a squeeze of lemon or lime is another excellent choice, as it adds effervescence without getting in the way of the bourbon’s flavor. When you’re ready to experiment, you can buy a bottle online and discover your perfect simple pairing.
The Final Pour: Is Double Oak Bourbon Right for You?
So, you’ve learned about the double barrel process and how it creates those deep, rich flavors. Now comes the most important question: is a bottle of double oak bourbon the right addition to your home bar? This style isn’t just about a unique aging method; it’s about a specific taste experience. It’s for the drinker who craves more complexity, a smoother finish, and a story in every sip. Let’s break down who this bourbon is for and whether it fits your palate and your budget.
Who Will Love Double Oak Bourbon?
If you’re just starting your bourbon journey, a double oak can be a fantastic guide. It’s often approachable yet packed with the rich, sweet flavors of vanilla, caramel, and toasted oak that many people look for in a quality whiskey. For seasoned enthusiasts, it offers a consistently satisfying and well-rounded profile that never disappoints. This style is perfect for anyone who appreciates meticulous craftsmanship and wants a bourbon that feels both classic and a little bit special. It’s a reliable choice for a weeknight pour but special enough to share with good company.
What Drinkers and Critics Are Saying
The consensus on double oak bourbon is overwhelmingly positive. It’s often described by reviewers as a consistently good and satisfying drink that delivers a richer experience than many standard bourbons. While the core expressions from respected distilleries are praised for their quality and balance, some critics note that certain limited-edition versions can come with an absurdly high price tag that doesn’t always match the value. Overall, the style is celebrated for its ability to deliver a dependably delicious and complex sip, making it a trusted favorite among many whiskey lovers.
Where to Find It and What to Expect
One of the best things about double oak bourbon is its versatility. It’s robust enough to be enjoyed neat or with a single large ice cube, but its sweet and spicy notes also make it a fantastic base for classic cocktails like an Old Fashioned or a Manhattan. You can find excellent examples of this style, including our own Mary Dowling Double Oak Barrel, at most well-stocked liquor stores. If you’re looking for a specific bottle, you can always use our store locator to find a retailer near you. Expect to pay a bit more than you would for a standard bourbon, but the added complexity is well worth it.
Our Verdict on Value
When it comes to value, double oak bourbon punches above its weight. The process of using a second barrel adds time and cost to production, which is reflected in the price. However, what you get in return is a bourbon with significantly more depth, smoothness, and character. For many drinkers, the upgrade in flavor is more than worth the extra expense. It’s an investment in a more refined and memorable drinking experience. If you appreciate a bourbon that tells a story of patience and craft, then a double oak offers excellent value for the quality in your glass.

Frequently Asked Questions
What’s the main difference between a double oak and a regular bourbon? Think of it as the difference between a single coat of paint and a second, finishing coat. A regular bourbon gets all its flavor from one new charred oak barrel. A double oak bourbon completes that first aging process and is then moved into a second new barrel. This extra step doesn’t just make it older; it transforms the flavor, adding deeper layers of sweetness, spice, and complexity that you can’t get from a single barrel alone.
Does aging in a second barrel just make the bourbon taste like wood? That’s a great question, and the answer is no. The goal isn’t to make it taste overwhelmingly oaky. The second barrel is often heavily toasted before it’s charred, which caramelizes the sugars in the wood. This process brings out rich, sweet notes like vanilla, caramel, and dark chocolate, creating a beautifully balanced and smooth profile rather than a sharp, woody one. It’s all about adding depth, not just woodiness.
Is “double oaked” the same thing as “double barreled” or “twice barreled”? Yes, for the most part, these terms are used interchangeably within the whiskey world. They all refer to the same innovative process of aging a spirit in two separate, new charred oak barrels. Different distilleries might prefer one term over another for their marketing, but the craft behind the name is the same.
Is a double oak bourbon a good choice for someone new to whiskey? Absolutely. In fact, it can be a fantastic starting point. The double barrel process often smooths out any harshness and amplifies those delicious, dessert-like flavors of vanilla, caramel, and toasted marshmallow. This makes the bourbon incredibly approachable and easy to sip, offering a rich, flavorful experience without being overwhelming.
What’s the best way to start drinking a double oak bourbon to really appreciate it? To get a true sense of its character, I always recommend starting simple. Pour a small amount neat in a glass and let it sit for a minute. This allows you to take in all the complex aromas before you even take a sip. If you prefer it chilled, add a single large ice cube, which will cool the spirit down without diluting it too quickly. This is the best way to appreciate the craftsmanship before you decide to mix it in a cocktail.
